Answer:

Fossil Z is younger than Fossil Y.

Explanation:

For any age-related questions in geology, we have to consider the basic principle of stratigraphy. According to which, sediment layers on top harbor younger fossils whereas layers on the bottom have older fossils. In the case given here, Fossil Z is younger because it is in the top layer and Fossil Y is in the middle layer. The other two options are completely wrong because Fossil Y cannot be older than Fossi X and likewise, Fossil Z doesn't exist in multiple periods rather it is present only once.

timurjin [86]

Answer:

Explanation:

Because the newts with this mutation have faster reflexes, they are able to evade predators much better than the normal newts. This increases their chances of survival hence are more likely to reach reproductive age than the normal newts. Therefore they have a higher probability of passing their genes to the next generations. With each generation, newts with the mutated gene will increase.
